Mouse myeloma cells were fused with spleen cells from mice that had been immunized with a human ependymoma derived cell line, KMS II. Hybridomas producing monoclonal antibodies (MAbs) were screened and cloned. Specificity of the antibody was determined by enzyme-linked immunosorbent assay (ELISA) and/or indirect immunofluorescence assay. One of the MAbs, designated Ep-C4 (subclass = IgG1), reacted with two cell lines derived from ependymoma but did not react with 17 cell lines derived from other types of brain tumor nor with 4 neuroblastoma cell lines or 19 cell lines derived from carcinoma, hematopoietic tumors and amnion. Indirect immunofluorescence and immuno-electron microscopy studies revealed that the antigen recognized by MAb Ep-C4 was located on cell surface membrane. The membrane antigen of KMS II cells, immunoprecipitated by MAb Ep-C4, was a protein of 81,000 dalton. The reactivity of MAb Ep-C4 was further examined using immunofluorescence and/or immunoperoxidase methods and frozen sections and short-term cultures of various types of brain tumors. No cross-reactivity with normal adult or fetal brain tissues was detected by absorption assay and immunoperoxidase staining. Our results suggest that the antigen defined by MAb Ep-C4 is specific for ependymoma cells, and different from the antigens of glioma cells or other neuroectodermal-derived cells previously described.

Fifty cases of nonimmunologic hydrops fetalis found in Japanese infants are reported. Nonimmunologic hydrops fetalis is associated with various pathological conditions, twin transfusion syndrome including acardiac monsters, fetal heart diseases, congenital cystic adenomatoid malformation, pulmonary sequestration, pulmonary lymphangiectasia, intrauterine infections such as cytomegalovirus infection and neonatal hepatitis, congenital neuroblastoma, Kasabach-Merritt syndrome, cystic hygroma, and chromosomal aberrations. The mechanism of hydrops fetalis found in these conditions is discussed from various viewpoints. Despite a careful examination, no causative conditions were found in 14 cases. The placenta showed a proliferation of Hofbauer cells that were strongly positive for immunoreactive alpha 1-antichymotrypsin and there were other common findings such as edema of terminal villi and fibrin thrombi.

Here we report a patient with stage-4 bilateral cystic adrenal neuroblastomas with disseminated liver metastases and consumption coagulopathy who underwent liver transplant. Our patient was initially diagnosed with infantile hepatic hemangioendothelioma and bleeding into the adrenal glands secondary to consumption coagulopathy (Kasabach-Merritt syndrome). Liver transplant was performed as a life-saving procedure under this diagnosis. We discuss this unique patient because of the diagnostic pitfalls of this rare disease and the successful clinical outcome after LT and subsequent chemotherapy for neuroblastoma.
